Definitions

  • the invention relates to a syringe for dispensing flowable and / or highly viscous materials having a syringe barrel having an outlet nozzle, a material container disposed therein, a handle disposed at the opposite end of the syringe barrel, and a syringe plunger movable into the syringe barrel through the gripping member.
  • Such syringes are already known from EP 225 265 A1.
  • This document discloses a syringe for injecting pasty products, in which a sample tube is arranged in a cylinder, the sample tube having a slit comprising a substantial part of its circumference, with the aid of which material can be scraped from a mixing plate and brought into the cylinder , This material is pressed by means of a slidable piston through the top of the cylinder and thus injected at the treatment site.
  • Object of the present invention is to provide a comparison with the prior art improved syringe, which can be safely operated even when larger pressures.
  • the object is achieved in that the handle is arranged by means of a thread on the syringe tube and that the material container has a closed lateral surface.
  • the force of the syringe plunger can be optimally transferred to the material arranged in the syringe, without the risk of tearing the outlet nozzle or tearing open a part of the syringe tube.
  • the double wall thickness improves the stability and durability of the syringe.
  • the one end of the material container is arranged on the outlet nozzle and in the opposite end a plug which is movable between the ends is arranged, the end of the syringe piston which can be moved into the syringe being designed to bear against the stopper.
  • the force is transferred by means of the plug from the syringe plunger to the material in the syringe. It is easily possible to form the plug sealingly with the wall of the material container final, this seal does not need to be ensured by the syringe plunger itself, so that it can be made simpler and less expensive.
  • the lateral surface of the material container is dimensionally stable, wherein the ends of the material container can be designed to be open.
  • the material container from a flexible material such as a plastic film may be formed, wherein at its handle end facing a movable in the syringe barrel plug may be arranged so that the hineinbewegbare into the syringe end of the syringe plunger to the plant is formed on the plug. It is of course also possible to transfer the pressure from the syringe plunger directly to the flexible material, wherein the syringe plunger must be designed to be sealing in a suitable manner and to the wall of the syringe barrel.
  • the outer diameter of the material container is about the same size as the inner diameter of the syringe tube, so that both tubes abut each other with the least possible play and reinforce each other.
  • the syringe can be formed, for example, of plastic.
  • the syringe body and the outlet nozzle are integrally formed.
  • both parts can be manufactured for example by injection molding in a single operation.
  • the connection between the outlet nozzle and the syringe tube, which is generally highly stressed when pressure is applied, is capable of absorbing the high pressures encountered during operation without tearing the tip off the tube.
  • the invention further relates to the use of the described syringe for receiving and dispensing dental materials.
  • FIG. 1 shows a syringe according to the invention in an exploded view (Fig. 1) and in the assembled state (Fig. 2) in each case in section.
  • an outlet nozzle 2 is monolithically arranged by both parts are prepared for example in one operation by injection molding.
  • the outlet nozzle 2 has an outlet opening 3, which varies in size and the flowability or viscosity of the material is adjusted, this adjustment takes place during injection molding.
  • the outlet opening 3 is closed with a cap 4.
  • a plug 6 is first inserted and pushed against a stop 7. Thereafter, dental material is filled into the material container 5 and this pushed into the syringe barrel 1.
  • the syringe tube 1 has at its one end a thread 12 onto which the handle 8 is screwed.
  • the material container 5 is slightly (several tenths of a millimeter) longer than the cylindrical interior of the syringe barrel 1, so that its one end protrudes from the syringe tube 1 by this length.
  • the syringe tube 1 When screwing the handle 8, the syringe tube 1 is pressed against the end face of the material container 5 so that it is pressed firmly against a stop shoulder 9 at the junction of syringe tube 1 and outlet nozzle 2. This ensures that no material from the material container 5 penetrates into any intermediate space between this material container 5 and the syringe tube 1.
  • the syringe plunger 11 may have markings along the thread for orientation about the position of the plug 6 within the material container 5 and thus for orientation on the degree of emptying of the syringe.
  • the plug 6 itself can also be formed directly on the syringe plunger 11. In this case, the stop 7 of the material container 5 is eliminated.
  • All parts of this syringe are formed from a dimensionally stable plastic, but may also be formed, for example, of metal.
  • the material container 5 may be formed from a flexible material, for example a foil bag.
  • the stopper 6 is placed in the syringe tube 1 in a form-fitting manner.
